APPLICATIONS
The URA_D-10W/ URB_D-10W Series are
specially designed for applications where a
wide range input voltage power supplies are
isolated from the input power supply in a
distributed power supply system on a circuit
board.
These products apply to:
1) Where the voltage of the input power
supply is wide range (voltage range
≤4:1);
2) Where isolation is necessary between
input
and
output
(Isolation
voltage
≤
1500VDC);
3) Where the regulation of the output
voltage and the output ripple noise are
demanded.

*Input voltage can’t exceed this value, or will cause the permanent damage.
**Test by nominal Vin and constant resistive load.

APPLICATION NOTE
Recommended Circuit
All the URA_D-10W & URB_D-10W Series
have been tested according to the following
recommended testing circuit before leaving
factory. This series should be tested under
load. Never be tested under no load (see
Figure 1).

TYPICAL CHARECTERISTICS
Temperature Derating Graph
If you want to further decrease the output
ripple,
you
can
increase
capacitance
properly or choose capacitors with low ESR.
However, the capacitance should not be too
high. (Table 1).
